Search101 – What is it?

“Search101” search hijacker is a potentially unwanted application (PUA)1, that is promoted as a plugin for your internet browser. It is typically shared as an add-on for Chrome or Firefox, that assists to browse some particular information, for instance, about sport events, make your web browser much more secure, enable downloading of any kind of web video, and so on.

However, the “Search101” plugin is quite pointless because all such features are currently built-in to your browser and/or system. Such marketing mottos are targeted at low-skilled computer users, for example, pensioners or schoolchildren. But often even skilled users are getting caught on such a lure. In specific instances, this hijacker is distributed together with free programs.
